Advice please - Victorian house

[Spicypumpkinlatte]

Hello everyone would someone give me a bit of advice please? I need to get the external walls of my Victorian property re-plastered because the current one (original plaster) is crumbling away in the top (3rd floor) sitting room. I have a quote from a plasterer who suggested putting insulation boards in place because the place is constantly freezing with original single glaze windows. Then I have done a bit of reading and some places seem to suggest lime plaster is the recommended option to prevent damp problems and some say it's fine to have modern plastering in top rooms. There is no damp in the house apart from a very small stable area next to the kitchen, with the kitchen being the warmest place in the house (which has modern plastering). Does anyone have any experience with a similar situation? Many thanks in advance!!

Speak to more tradespeople so you have more than one opinion. If you have neighbours who have houses of a similar build to yours, got and have a chat with them.

Get them insulated. If the rooms are bone dry and the exterior brickwork in good order, it will be fine. Are you getting double glazing as well?

I wish! The building is listed, so double glazing isn't allowed (as far as i understand)

I would be very careful getting insulation especially as it's a listed building. If it's not done correctly it could cause damp and mould. Have you only had one quote?

You can fit secondary glazing. It works surprisingly well if done properly.

There are some good FB pages advising on this sort of thing for period houses. Might be worth a search. Lime plaster is frequently recommended. I've lived in a listed Victorian house and put in secondary glazing. You'll have to get planning permission, but it makes a huge difference to both temperature and noise.

Can you get double glazing in wood frames to match the original frames? I've just had this done in a 1930's house.
